US S14 240SX Factory Front Suspension Crossmember: KA24DE Cradle, Interface and Condition Identification

54401-65F00 -> 54401-85F00 is the only whole-member replacement relationship asserted. Both identities are shown for the checked US 1995-1998 240SX KA24DE application; current catalog pages mark them discontinued. No relationship is asserted to either S13 family, imported S14/S15 catalogs, RHD rack placement, non-KA engine mounts, tubular aftermarket members or modified swap cradles. Shared adjacent bolts, arms, brackets or seller compatibility labels do not broaden this chain.

Start with recipient and donor 17-character VINs, US/LHD identity, 1995-1998 S14 production and factory KA24DE equipment; photograph the whole member and every readable number before purchase. Confirm the rack saddle, bushing and bracket arrangement; engine-mount stands and holes; transverse-link/lower-control-arm pivots; tension-rod brackets and brace points; stabilizer mounts; body mounting pads, sleeves, bolt holes and locating surfaces; and clearance to the pan, steering shaft, lines and exhaust. Require a written bare-versus-loaded inventory covering rack, brackets/bushings, lines, engine mounts, control arms, tension rods/brackets, stabilizer, braces, shields and all hardware. Reject or obtain qualified structural engineering approval for bent/twisted members, shifted pickup points, cracked welds, elongated or torn holes, severe scale/perforation, collision heat/filler, undocumented straightening, cut/welded reinforcement, rack relocation or swap modifications. Compare diagonals and body-repair datums and require a qualified collision/suspension inspection; a visually clean used member is not geometry proof. Support the vehicle and powertrain with rated equipment, follow the current factory procedure and torque sequence, final-tighten loaded suspension joints as specified, then perform steering-centering, clearance and four-wheel-alignment checks before road use. Do not infer S13, imported/RHD, S15 or engine-swap interchange from 54401-85F00 seller headings.

A verified straight factory 54401-65F00 or 54401-85F00 member is the default restoration path. A professionally measured and repaired original may be considered only after qualified structural/collision approval and documented datum results. Tubular or motorsport K-members change engine, rack, suspension, stiffness, crash, alignment and road-use assumptions; they are outside this factory-identification page and require manufacturer application proof, engineering review and jurisdiction/insurer approval. Powder coat or paint can conceal heat, filler, cracks and corrosion, so inspect bare critical interfaces and preserve drain/attachment features. No swap, steering-relocation or competition conversion is recommended here.

US/LHD 1995-1998 S14 KA24DE factory-member identification only. Verify VIN/build, readable 54401-65F00 or 54401-85F00 identity, every mounting interface, geometry, collision/corrosion/repair condition and exact bare-versus-loaded contents. This is not structural-repair instruction and does not claim S13, imported/RHD, S15, engine-swap, tubular-member or rack-relocation interchange. Have a qualified collision/suspension professional approve the member and alignment before use.
